This book describes the problem of environmental pollution and waste management in shipbuilding and ship repairs. The shipbuilding industry is one of the hardest metal industries with several chemical and hazardous material exposures. Most of the traditional production processes such as welding, painting, blasting, and fiberglass production have direct impacts on workers' health and safety as well as adverse effects on the environment.

Machining is the most important of the manufacturing processes. Machining can be defined as the process of removing material from a work piece in the form of chips. The term metal cutting is used when the material is metallic. Most machining has very low set-up cost compared to forming, molding, and casting processes. However, machining is much more expensive for high volumes. Machining is necessary where tight tolerances on dimensions and finishes are required. Experiential procedure for all machine tools.
